Passport Ultra 3T is frequently ejected by the MacBook Pro (OS 10.11.6) Light blinks very rapidly. By pushing cable into port it makes a more secure connection and shows up in the Finder. After a while it’s rejected again. Same problem with other cables and plugging into a different Usb hub port. Bought last fall 2016. Can ithis external be replaced.
Have you tried with a Micro USB 2.0 cable as opposed to other USB 3.0 cables? Some Mac systems have issues with USB 3.0 devices due to Apple’s push for Thunderbolt and Lightning.

Thanks, No other cables work. I will create an RMA for this external.
